    摘要: The present invention relates to a method of preparing an aerosol suppressant composition and to use of the composition to reduce or suppress silicone mist in high speed coating processes and significantly increase the adhesion of the coating to the substrate. More particularly, the present invention relates to a method of preparing an aerosol suppressant composition by reacting an organosilicon compound, an oxyalkylene containing compound, and a catalyst. The composition, when added to curable silicone coatings, reduces the amount of silicone mist in high speed coating processes.
